I've been playing with Angular2 and tried to find a way to use pub/sub
mechanism, across the whole component tree.
It seems that EventEmitter is only emitting an event that can be subscribed
to one level up - but not more. Similarly, it only emits the events up the
tree, but now downwards.
plunker here:
http://plnkr.co/edit/gputAG?p=info
see
class App {
onAncestor($event) {
console.log('in ancestor, decendent clicked',$event);
}
}
...
class Entities {
....
onParent($event) {
console.log('in entities parent, child clicked',$event);
}
onGrandParent($event) {
console.log('in grand parent, grandschild clicked',$event);
}
}
only onParent is called, never onGrandparent or onAncestor
similarly it wont publish downwards
I wonder how to do it
thanks for any idea
